Hi all --
Please note that - from hereon - our ongoing discussion about backwards compatibility and missing DPI-awaress in older images can still be resolved in various ways:
a) Tag some older OSVM version as "good enough" where the prior -metal platform code did provide a "low resolution" mode -- by accident -- to accommodate macOS 12.x and Retina displays
b) Implement a cross-platform "low resolution" mode in the OSVM, where that mode might be chosen through an extra bit in the image header; then make another OSVM release
c) Rely on platform tools to workaround older images being unaware of high-resolution displays and thus appearing quite tiny; i.e., the global macOS 12 magnifier still works

We just released the next version of the OpenSmalltalk VM.
Please find the binaries here: https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/tag/202205110711 [https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/tag/202205110711]
(see VMMaker.oscog-mt.3184 and update.oscog-mt.6.mcm)
That version will be used in the upcoming Squeak 6.0 and also updated bundles for Squeak 5.3. And probably in upcoming Cuis releases. :-)
Here is an attempt of a change log (since 2020): - Adds ARMv8/Aarch64/ARM64 JIT incl. support for Apple M1 - Adds "fast C primitives" via #FastCPrimitiveFlag
- Adds support for catching exceptions in FFI callouts - Adds #primitiveScreenScaleFactor (for DPI-aware images) - Adds primitives 568 and 578 complementing 88 (primitiveSuspend) - Adds #primitiveMultipleBytecodeSetsActive to update image format for SistaV1 - Adds VectorEnginePlugin - Fixes regressions in ARMv6 support - Fixes performance regressions of -metal and -opengl backends on macOS - Fixes -core-graphics backend on macOS - Fixes Retina scaling on macOS, i.e., support "backing scale factor" - Fixes primitive 126 to fail on graphics backends w/o composition buffer - Fixes regressions in vm-display-fbdev on Linux - Fixes time sync (e.g., for DST) on Windows - Fixes UDP binding on Windows
I am sure that I forgot something especially in plugin code. Please expand on this.
BIG THANKS to everybody who has worked on this release! Personally, I would like to thank Eliot, who is a great software architect who keeps on making the OSVM faster with every commit. Thank you!
Best, Marcel (on behalf of the OSVM core dev team)
